I get so sick of people using the excuse that it's just a theory because they obviously don't understand what that means. A theory is not just some concept someone thought up one day and everyone then said, "yeah that sounds good we'll use that." Technically in biology, which is the realm of science evolution falls under, there are no laws like in physics. Very few things can actually be "proven" in biology. Theory is actually as high as it goes, once something makes theory it means it went through tons of research and tests to make it this far. Many many aspects of evolution can be proven, and that's why it continues to exist. Nothing has been disproven, it just hasn't yet been implicitly proven. And, seeing as how many of the things that we can prove about biology, evolution, and history directly contradict most religions, by scientific viewpoint, we have disproven religion.
